Abstract

Objectives:

This study aimed to compare the reporting of high-resolution computed tomography of temporal bones for otosclerosis by general radiologists and a neuroradiologist within a local National Health Service Trust.

Methods:

A retrospective case review of 36 high-resolution temporal bone computed tomography images obtained between 2008 and 2015 from 40 otosclerosis patients (surgically confirmed) was performed in a district general hospital setting. The main outcome measures were correct identification of otosclerosis by high-resolution computed tomography and adherence to the petrous temporal bone imaging protocol.

Results:

Correct diagnosis rates were significantly different when made by general radiologists vs a neuroradiologist (p < 0.0001; two-tailed Fisher's exact test). None of the high-resolution computed tomography scans adhered to the temporal bone imaging protocol.

Conclusion:

The use of high-resolution computed tomography for suspected otosclerosis is helpful for diagnosis, disease staging, obtaining informed consent, surgical planning and prognosis. This study suggests that radiological detection of otosclerotic changes by high-resolution computed tomography of the temporal bone is significantly better when performed by a dedicated neuroradiologist than by a general radiologist. Use of a standardised temporal bone computed tomography protocol is recommended to provide consistently high-quality images for maximising disease detection.
